Not a Scrap of Steel
On the Subframe, the toe cap, the shank, and every piece of hardware are non-metallic. That takes weight out of the boot, keeps the toe box from going cold on a winter morning, and leaves nothing to rust when the leather stays wet.
Light Without Giving Up Protection
The composite toe meets the same ASTM F2413 impact and compression thresholds as steel, and the EVA midsole and cement construction keep the whole boot light and flexible underfoot from the first day.
Why Choose the CA5551?

Frequently Asked Questions
Is the CA5551 static-dissipative (SD)?
It isn't. The CA5551 is Electrical Hazard rated, which is a different property: EH insulates you from live circuits, while SD deliberately conducts static charge to ground. If your workplace requires SD footwear, choose an SD-rated boot instead.
Does it have a zipper?
The CA5551 is a standard lace-up with non-metallic hardware, without a side zipper.
Why choose non-metallic hardware?
Non-metallic hardware won't rust when the leather stays damp, and together with the composite toe and shank it keeps the boot fully metal-free.
How long does the waterproofing last?
The SCUBALINER™ is a sealed membrane rather than a surface coating, so it doesn't wash off. Conditioning the leather and keeping the seams clean is what keeps it working over the life of the boot.
Does the EH rating still apply when the boots are wet?
Treat it as reduced. EH testing is performed under dry conditions; water, damp leather, and worn outsoles all degrade insulation. EH footwear is secondary protection, never a replacement for de-energizing a circuit or primary PPE.
What widths does the Subframe 6" come in?
It comes in Medium, Wide, and Extra Wide, in men's sizes 8 through 14.
